* Force uncached status update if any items in selected aren't up-to-date
* Removed Refresh option since it's done every time the menu is opened
* Make Source control menu update state asynchronously so menu doesn't stall
* Update Checkout to Sync and Checkout so it can all be done at once
* Add Partial Checkout state when files are selected and show users locking files in tooltip
* Add options to Make Writeable and Revert Writeable
* Add error state if source control is unavailable
* Hide options, like checkout, that are not available for the current SCC provider
* Always show all options so users can learn bettern muscle memory
* Add Warning when doing any source control option on selections larger than 25 (currently hardcoded)
* There's still some slight difference in behavior between file and folder selection. If only files are selected the async update will not show any options availabe until the full scan is done and there are some additional features like partial checkout. If there are any folders then options become available the moment one asset is available for an action.
#tests Tested all button scenarios, tested small and large sets of folders, assets and a mix.
